Yamaha MT-03 (2015+) Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the 2015+ Yamaha MT-03.

The MT-03 was refreshed externally in 2020, but the maintenance is the same as former years.

The Yamaha MT-03 is based on a liquid-cooled 321cc parallel twin with dual overhead cams and 4 valves per cylinder. It’s a spritely motor. With a 11.2:1 compression ratio, it puts out a peak of 30.9 kW (41.4 hp) at 10750 rpm, and peak torque of 29.6 Nm (22 lb-ft) at 9000 rpm.

It’s very similar to the maintenance schedule for the Yamaha YZF-R3, which shares the same engine and components.

Yamaha updated the MT-03 with a styling make-over for 2020. It got inverted front forks and a redesigned front light to match the 2020 MT-09 and MT-10. But the maintenance schedule is unaffected. The MT-03 still has a single brake disc up front.

What you need to service the Yamaha MT-03

If you’re doing scheduled maintenance on an MT-03, you at least need basic motorcycle maintenance tools.

Aside from that, for the Yamaha MT-03, the manual recommends the following specific consumables.

PartYamaha MT-03/YZF-R3 Spec
Engine oilYamalube 10W-40 or Yamalube 10W-50 as recommended by Yamaha. The manual suggests it and it’s affordable on Amazon with a solid 5-star rating. Other lubricants would do, e.g. Motul 7100 10W-50 or Mobil 1 Synthetic, but that’s your call. Don’t over-torque the bolt (spec is 20 Nm/15 lb-ft per the manual) — use a torque wrench if you don’t have experience with how much torque is enough.
Oil filterNeeds to be changed every time you change the oil. Either get a stock one (part 5GH-13440-50-00, used for many Yamaha products) or the Hiflofiltro HF204RC. Torque is 17 Nm/13 lb-ft.
Engine coolantYamaha recommends “Yamacool”, but use any 50/50 ethylene glycol pre-mix.
Spark PlugsNGK CR8E. This is what the manual and mechanics suggest. Make sure it’s gapped correctly to 0.7-0.8mm (get a gapping tool) and torqued to 18 Nm/13 lb-ft (new) or 13Nm/10 lb-ft (after checking).
Air filterYamaha part number 1WD-E4451-00. You can also get the K&N equivalent, YA-3215.
Brake padsI recommend EBC double hardened brake pads for extra life and better brake feel. For the R3 and MT-03 you need one set for the front (FA663HH) and one for the rear (FA662HH).
Chain maintenanceMotul chain paste — one of the most highly-regarded chain lubes. Easy to apply, doesn’t fling off. If you need more stuff, get the Motul chain care kit as an affordable package.
Cable lubeUse Protect all cable life to lubricate your cables and controls.
GreaseAlways good to have on hand lithium soap-based grease for lubing external pivot points (like the swingarm) and bearings.

Yamaha MT-03 Maintenance Schedule

Below is the maintenance schedule for the Yamaha MT-03.

The maintenance schedule is a bit different for US and Europe models.

  • US models: 3000 mile and 6-month service intervals
  • Europe models: 5000 km and 5-month OR annual service intervals.

The maintenance schedule for the MT-03 is also quite different to that for the YZF-R3, particularly in Europe, even though they share a lot of common parts.

Notes on the maintenance schedules

  • At the end of the maintenance schedule, keep repeating the same maintenance schedule periodically.
  • Yamaha would prefer you to only service the chain, change the oil, and grease external points, leaving other work for qualified professionals for safety reasons.
  • See the European schedule below for the kilometer intervals
  • Items marked [Y] need specialist diagnostic tools that dealers have.

About the Yamaha MT-03

The MT-03 is a pocket rocket, a standard (or “Naked”) motorcycle based on the very successful YZF-R3’s engine and chassis.

Even though it’s based on a small engine, the Yamaha MT-03 is sized like a full-size motorcycle. The frame, handlebars, wheels, and tyres all look correct — not like a downsized standard.

So the Yamaha MT-03 is ideal for new riders who want to get on to a bike that’s fun, quick, and feels cool. That feeling’s important!

The 321cc liquid-cooled, inline 2-cylinder engine rips through the rpm range. Its 180-degree crank design (where it goes bang-bang-bang-pause-pause) is balanced by an integrated counter-balancer, which means that the engine has minimum vibrations in most everyday parts of the rev range.

Even though the engine is only 321ccs and produces “only” 42 hp (31 kW), the MT-03 is a lot of fun to ride hard — something you can’t do on larger bikes without ending up in illegal speed territory. It produces enough torque down low, but is very rewarding to ride up high in the rev range.

Experienced riders who get on the MT-03 end up liking it, even if most people don’t switch to it for their main ride. It’s frugal on gas, easy to maintain, and very easy to flog.

While the suspension and brakes specs are low, the bike is lightweight, which means that the suspension is comfortable and the brakes are adequate for everyday riding.

In 2020, Yamaha updated the MT-03. They kept the core of it — the 321 cc parallel twin and every riding spec.

But the new 2020 Yamaha MT-03 got

  • Upside-down forks — still not adjustable, but they make for less unsprung mass up front
  • New shock settings to match
  • Redesigned front lights — an LED headlight and slant-eye front lights
  • LCD instruments
  • LED flashers

Overall it’s much the same bike, and the maintenance schedule remains the same.

Manual for the Yamaha MT-03

The above information was gleaned from the owner’s manual for the 2022 Yamaha MT-03 from the US and the 2020 manual from the Europe spec MT-03.

The maintenance schedule remains much the same as previous years.

Yamaha updated their MT-03 maintenance schedules for Europe. It used to be a lot more aggressive.

Below is the old / superseded maintenance schedule for Europe. Yamaha has retrospectively gone and updated all its manuals. This old maintenance schedule is much more aggressive.
